i second that, chemical bros are the best! i can shred to brotherhood (album by them) any day

check out slim thug is a bit electronic and is hip hop mixed to it, check out the album Boss of all boss's by him

for electro/dance/d+b, browse through on youtube for BBC Radio 1's essential mix, its the shits, 2 hour mixes and you can usually get them through google or on a blog somewhere. Alex metric is a good one, its worth a look
